Hi, today I encountered this video about fixing the e-brake failure. For this guy with this car it was so easy and completely free of charge! I know a lot of us have had this problem with our z4s, including me. As far as I know and from my own experience, only a software issue was able to fix the e-brake failure. However have a look at this video...makes me think if somehow ours could have been fixed this way too. I really dont know if its possible for our cars but its very interesting to see that this simple thing could have avoided us from a lot of hassle! Let me know what you think guys...

Hi, not sure if this is related to the issue with ebrakes that seem to affect z4’s?
From what I’ve read, it seems to be a below par battery that triggers the issue & renders the software faulty requiring an updated version to be applied at the dealers.
I’d be surprised if a reboot is going to fix that, it won’t hurt to try it though as it’s quick & cheap
